S5620 (Monte) doesn't seem to play ball with TB. It just seems unable 99% of the time to get a GPS lock despite the bundled / pre-installed phone apps finding up to 6 satellites and showing correct position after just a few seconds every time without fail. Even when left for over 10 mins TB fails to get a lock.

Even stranger though is that it has, on 3 very well spaced occaisions, achieved a gps lock and then of course the rest of it runs perfectly. That's why I haven't yet given up on TB with this phone. Once you have a GPS lock stopping then restarting the GPS doesn't result in a quick lock as I had expected (as happens with my Samsung Android) - you're back to square one and maybe a handful of times out of 100 attempts you will get another GPS lock if you're lucky. No errors show at any time in the Info --> Technical page from what I can see.

I've searched through the forum and translated the foreign threads relating to this phone and tried all of the suggested settings but nothing has made any difference so far. Hope you eventually figure it out Krutch, it would be nice to get it working as well as it does on my android

Some info I gathered using TB 1.0.5 on S8500 wave (see device thread for more)
-- signing doesn't work, I don't know why. I will try workaround using file TKFile explorer when I find some free evening.
-- internal GPS doesn't connect. In info there is security exception, seems TB is not allowed to use API in question. I don't know which one and what has to be set in JAD file. Maybe it doesn't work until it is signed correctly???
-- there are some troubles with stability using bluetooth: when you connect both handsfree and GPS module, receiving a call means TB stops (?). After hang up (probably ) there is slow beeping and icon is blue instead of green. GPS module indicates it is connected. Waiting doesn't help (some minutes). To make it work again, one has to stop GPS in TB menu and start over again (it takes some time to stop), in worse case also GPS module or everything needs to be restarted (GPS module, bluetooth of phone and TB itself - which is not funny on a highway with those security messages ) I suspect some troubles with phone bluetooth itself since similar problems I have with Nokia N96, which is Symbian based. I don't know if anyone experienced such behavior, maybe it is a unique mix of devices (Jabra BT530, Nokia LD-4W)

UPDATE: this happens regardless of handsfree connected or not - just receiving a call is sufficient. I suspect when TB is put in the backgroung, it survives some short time, than bluetooth is switched off (?). Upon activate, exception like "provider error" or something like this is shown in technical info. This behavior is similar to what I see on Nokia N96 which is Symbian based. I don't know anything about implementation TB is using for bluetooth device (listener? separate thread?) my solution would be: in case of such error, display message "Try again? (yes/no)". This would be great since it would require one single click. Message will probably hang along with app in background, when activated in task manager this would solve the problem. Just guess, though...

-- some maps don't display correctly. Only a few of the tiles is displayed, the rest of the screen consists of grid with some text labels (name, size etc.). I don't know if the problem lies in memory (I tried several settings combination), I suspect problems with Samsung renderer itself (if Kruch is using some internal API to display PNG). The troublemaker is for example Prague 1:10000. Similar problem I experienced with CMS font size - until some size (big one, last usable I found 3000x193px) it gets displayed, then only icon is visible in phone media browser and CMS is using default font. If internal picture viewer renders file correctly, it is displayed in CMS also.
-- backlight is always on while GPS is started, no way to stop it or adjust (other than locking the phone). This is a very minor issue, since Amoled consumes less power and is quite visible even on low settings. After some 4 hours, using simultaneously music player, battery is still half full (using external BT GPS module).
-- for tared atlases, there are some exceptions when you set Misc settings incorrectly (like bad header, 20 20 20... I assume spaces . To make it work, everything in Misc menu has to be switched off, except "Safe renderer" (which probably has nothing to do with file reading)

some maps don't display correctly. Only a few of the tiles is displayed, the rest of the screen consists of grid with some text labels (name, size etc.)

This only happens to layers or maps with a huge number of tiles. For example higher zoom levels or bigger maps. Belongs this problem to TrekBuddy or Mobile Atlas Creator 1.8?
Untared one is running well but thousend of tiles will appeare as picture in the viewer of the phone and reading data of the SD card is getting realy slow at phone boot.

i have been usiing TB with my M8800 Pixon
- fullscreen works with adding a line MIDlet-Touch-Support: True in jad file and it realy work, no soft keys
- i tried the voice navigation and it works just fine
- after some changes to phone setting is internal GPS really fast to locate satellites outdoor or in car behind front window
- similar problem with calculating distance and avg speed as it was mentioned in S8000 Jet
- some problems appears in versions 0.9.99 and 1.0.0 - application just doesnt work
- last fine workong version is 0.9.98

Hello pitoz or anyone else having trekbuddy installed on a samsung pixon.

Can u tell me how u installed it? Because i don't understand anything from the wiki or the user guides..

I've been using it on Samsung Xcover 271 (B2710) with great success. I had to enable "lowmem IO" and "numeric input hack". Everything works and it even loads a gpx with 10100 pois. I had a couple of crashes (phone resets) but I think it could be SD card since phone crashed a couple of times while browsing files and also the card is unusually slow with large numbers of small files.

Recently installed TB on the phone of my friend, but I can not connect it to an external GPS receiver via Bluetooth. GPS is paired with the phone and is listed on the Bluetooth devices in the phone. GPS was also added to the trusted devices. Unfortunately positioning options to choose from TB is only a "stream" and "simulator".
Is there any way to connect the TB external GPS in this phone?

Samsung Rugby III (sgh-a997) phone i've managed to install TB (1.2.4) over the air only. had to write simple html page with link to TB jar file. device lock TB access to GPS and maps on memory card. it seems unsigned app is issue in this case. can't solve this problem at this moment.
